short patch across the base, then an almost straight transverse

Mr. Eaton found this common on a wall, partly overgrown 

 with lichens, at La Laguna, 22. II. 1904, and common amongst 

 lichen-covered trees, at Las Mercedes, 30. III. 1904. 



In the (5* the forewings are usually broader, and less conspi- 

 cuously marked than in the $, the pale spots and bands con- 

 taining a few dark scales, therefore less purely white, and frequently 

 smaller than in the .

Tinea immaculatella is by far the most abundant species in the 

 Island; it is evidently attached to Opuntia. Mr. Eaton made 

 the note : " Out of dead Agave (aloes). I believe they also feed 

 on dead Opuntia" The larva probably feeds on the fibrous inte- 

 rior of the dead, or half-dead, stems of Euphorbia canariensis, 

 , and Opuntia cochinelifera : I did not however observe it.
